一种用于大功率压接式IGBT的结壳热阻测试替代方法

Press-pack insulated gate bipolar transistors (PP IGBTs) is well suited for high-voltage, high-power applications due to their double-side cooling, ease of series connection, and higher power density. It is very important to measure the junction-to-case thermal resistance (Rthjc) for evaluating thermal performance, with high accuracy. However, the existing thermal resistance test methods will have...
